<code>defaultConnector</code> - a connector that is used by links if no <code>connector</code> property is defined on them. It can either be an object or a function. JointJS provides a collection of <a href="#connectors">built-in connectors</a> in the <code>joint.connectors</code> namespace; alternatively, a <a href="#connectors.custom">custom function</a> may be provided. See the <a href="#dia.Link.geometry.connector">link geometry connector documentation</a> for more information.
